Get the right fit in the Airexpert Y Longline Bra with a step-by-step band, cup and coverage check for yoga, Pilates and everyday wear.
Quick answer
The Airexpert Y Longline Bra fits correctly when the band sits level and snug without riding up, the longline hem stays put through overhead reaches, and the cups hold you without gaping or pressing. Start with your usual size, then adjust based on band tension and coverage.
Why the longline band changes your usual size check
A longline bra covers more of your ribcage than a standard bra, so the band does more of the supporting work. That extra coverage can feel firmer at first, especially if you are used to a thin-band sports bra. The goal is a band that stays in contact with your ribs all the way around, not one that digs in or lifts away when you raise your arms.
Because the Airexpert Y Longline Bra is designed for yoga, Pilates and everyday activewear, it prioritises comfort and low-profile support over high-impact compression. If you are between sizes, choose based on band comfort first and cup coverage second, since the longline hem will not adjust itself.
When to size up or stay put
Size up if the band leaves deep marks after a few minutes, if the longline hem rolls down when you sit, or if the cups press your bust flat. Stay with your usual size if the band is snug but comfortable and the cups sit smooth against your body. The Airexpert Y Longline Bra comes in XS to XL, though availability varies by colour, so check the colour you want before deciding.
Do not size down to chase extra compression. A too-tight longline bra restricts breathing during Pilates and can cause the hem to dig into your ribs. If you want firmer support for training, a different bra style may suit you better than forcing a smaller size in this one.
How to fit the Airexpert Y Longline Bra step by step
- 1. Measure your underbust and bust: Wrap a soft tape snugly around your ribcage just under your bust, then around the fullest part of your bust. Use both numbers to pick a starting size from the size chart. Common mistake: pulling the underbust tape too loose, which leads to a band that rides up. Write both measurements down before you order so you can compare if the first size feels off.
- 2. Put the bra on and settle the band: Fasten the bra, then smooth the longline hem down so it sits flat against your ribs. The band should be level all the way around, not higher at the back than the front. Common mistake: leaving the hem folded or twisted, which makes the band feel tighter than it is. Check the band in a mirror from the side; a level band is the first sign the size is right.
- 3. Check cup coverage and compression: Look for smooth coverage with no gaping at the top of the cups and no bulging at the sides. The Airexpert Y Longline Bra has built-in support, so you should feel held rather than flattened. Common mistake: accepting cup spillage because the band feels comfortable. If the cups gape or press, try a neighbouring size before deciding the style is wrong for you.
- 4. Move through your yoga or Pilates warm-up: Reach overhead, twist gently and fold forward. The longline hem should stay in place and the band should not lift away from your ribs. Common mistake: judging fit only while standing still. Any hem roll or band lift during these moves points to a size or band tension issue.
- 5. Do a five-minute wear test: Wear the bra for five minutes of normal activity. You should forget about the band, with no deep red marks and no need to tug the hem down. Common mistake: keeping a bra that only feels right when you stand perfectly still. If you are still adjusting it after five minutes, exchange it for a different size.
